Auralex Studiofoam Wedge Charcoal - 4 x 2 feet x 4" Single
2″ Studiofoam® Wedges™ are Auralex’s most popular Studiofoam® profile. They can be used to treat small to medium-sized areas, including vocal booths, control rooms and tracking studios. 2″ Studiofoam® is quite simply the workhorse of the industry and is your safest bet if you’re tuning your room yourself, without the help of a professional acoustician.
1″ Studiofoam® Wedges™ work most effectively on mid to high frequencies and may be used to acoustically treat walls or ceilings. They are twice as absorbent as 2″ Wedges™ at 125Hz.
3″ Studiofoam® Wedges™ can provide a well-controlled, more accurate sound in any size room.
4" Studiofoam® Wedges™ are recommended for rooms with pronounced low-frequency problems or where sonic accuracy is mandatory and maximum acoustic absorption is required (e.g., voiceover or drum booths, forensic audio labs and mastering rooms). 4″ Studiofoam® Wedges™ provide 3 times the low-end control of 2″ and can effectively tame even the worst sonic anomalies. In some instances, using 4″ acoustical Studiofoam® can lessen the need for significant, dedicated bass trapping.
